## What it is
A Python library providing Django-friendly finite state machine support, allowing declarative definition of states and guarded transitions on model fields. It has been renamed and superseded by viewflow.fsm as of version 3.0, which has a new, incompatible API.

## Use cases
- add a state machine to a django model
- enforce allowed state transitions in a workflow
- implement order status lifecycle in django
- prevent invalid state assignment on model fields
- model approval or publishing workflows in python

## When to choose
- you need declarative FSM transitions on Django models
- you want transition guards and TransitionNotAllowed enforcement
- you are maintaining a legacy project already using django-fsm

## When to avoid
- you are starting a new project - use viewflow.fsm instead
- you need a framework-agnostic state machine without Django
- you need a full workflow/BPM engine rather than a simple FSM

## Facets
- artifact type: library
- maturity: maintenance
- function: state-management, workflow-automation
- domain: web-development, backend, developer-tools
- platform: python
- tags: django, finite-state-machine, fsm, state-machine, transitions, viewflow
